DR. IR. MATTHIJN DE ROOIJ

University of Twente, The Netherlands

Short Biography:
After his Masters on laser hardening, Matthijn the Rooij has done a PhD on the prediction of galling in deep drawing processes in the University of Twente. In he has obtained the Corus Research Award in 2000, issued by the Royal Dutch Scientific Society. Currently, he is an associate professor in the chair of Surface Technology and Tribology of the University of Twente in the Netherlands. In this role, he is responsible for the research theme ‘extreme environments’.

Invited Speech: The potential role of interfaces and surfaces in the reduction of energy consumption

At this moment, there is a lot of attention for alternative sources and alternative storage possibilities for (electrical) energy, but also for making more efficient use of energy. In both aspects, but in particular in the efficient use of energy, well designed and engineered surfaces and interfaces can play an important role.   This role is much broader than friction reduction, but is for example also related to the utilization of hybrid materials in light weight constructions as well as the reduction of maintenance on industrial installations. In this talk, the focus will be on several ways in which surfaces and interfaces can contribute to a more efficient use of energy and examples will be given of recent research in this area.

ASSOC. PROF. IR DR ABU BAKAR SULONG

Universiti Kebangsaan Malaysia, Malaysia

Short Biography:

Abu Bakar Sulong, PEng, earned his DEng in 2008 from Sejong University (South Korea). He is currently Associate Professor at the Department of Mechanical Engineering, UKM. His research interest is mainly in material processing of nanocomposite, polymer composite and powder injection molding (powder metallurgy). He has published more than 100 research journal and technical papers with citation nearly 600 with H-index of 14. He has been invited as invited speakers and keynotes at national and international conferences. He is also actively being reviewers for local and international journals. He also grants evaluator at national level. Beside research, he actively involves as programme external examiner for local universities and institutes.

Invited Speech: Powder injection moulding of hydroxyapatite/titanium alloy (TI6Al4V) composite

Fabrication of Hydroxyapatite (HA)/Ti6Al4V composite had been less reported in PIM due to difficulty in processing of two type materials (miss-match between ceramic and metal). However, bioactive properties of HA and ductility of Ti6Al4V is important characteristics for implant material. Therefore, the main objective of this work is to investigate the feasibility of fabrication HA and Ti6Al4V composite through the PIM process. Rheology properties were investigated by capillary rheometer. HA/Ti6Al4V composite feedstock was moulded by low-pressure injection moulding machine. High vacuum furnace was used to diffuse HA/Ti6Al4V brown part at sintering temperature from 1100°C to 1300°C. Homogenous micro porosities was observed on sintered part. Optimization of sintering parameters was performed based on Taguchi method in variation of sintering temperature, holding time, heating rate and cooling rate. Sintering temperature exhibited the most significant factor on the properties of sintered part. Resulted mechanical properties of sintered are nearly in range of mechanical properties of bone implant.  HA has partially decomposed into β-TCP, titanium oxide and CaTiO3 from XRD analysis. Based on the results of this work, it can be concluded that fabrication of HA/Ti6Al4V composite through MIM process is feasible and can be further use as bone implant material.
